Question

Use the vertical line test to determine if the relation {(-6,-2), (-2,6),(0,3),(3,5)} is a function. Explain your response.

Answer 1

first plot all the points
then, according to the vertical line test, see if there are any locations on the graph where a vertical line can be drawn that crosses more than 1 point

"passes" the vertical line test (no vertical line crossing multiple points) --> function
"fails" the vertical line test (there is at least one vertical line crossing multiple points) --> not a function

see which one applies to your situation

Answer 2

I still do not understand. Is it functional or not.

Answer 3

have you made any attempt to plot the points, like I asked?
